**Explanation:** The audiologist explains the purpose and
procedure of the test to the patient, ensuring they understand what to expect.
-
**Informed Consent:** Obtaining informed consent is crucial before
conducting any audiological test.
2.
**Instrument Setup:**
-
**Audiometer Configuration:** The audiologist sets up the
audiometer, a device used to generate pure-tone stimuli at specific frequencies
and intensities.
-
**Bone Vibrator Placement:** The bone vibrator, a device
that delivers vibratory stimuli to the bone, is placed on specific locations on
the patient's head.
3. **Calibration:**
-
**Audiometer Calibration:** The audiometer is calibrated to ensure
accurate and standardized intensity levels for the pure-tone stimuli.
-
**Bone Vibrator Calibration:** The bone vibrator is calibrated to ensure
that the vibratory stimuli are delivered consistently.
4.
**Frequency Selection:**
- **Pure-Tone Frequencies:** The
audiologist selects specific pure-tone frequencies (e.g., 250 Hz, 500 Hz, 1000
Hz, 2000 Hz, and 4000 Hz) commonly used in audiometry. These frequencies cover
the speech range.
5. **Initial Air Conduction Testing:**
- **Baseline Testing:** Before
bone-conduction testing, the audiologist typically conducts air conduction
testing to establish a baseline for comparison. This involves using headphones
or inserts to assess the patient's hearing through the outer and middle ear.
6. **Bone-Conduction Testing:**
-
**Vibrator Placement:** The bone vibrator is placed on specific
locations, often the mastoid bone behind the ear or the forehead.
-
**Stimulus Presentation:** Pure-tone stimuli are presented through the bone
vibrator at varying frequencies and intensity levels.
-
**Patient Response:** The patient indicates when they hear the tone by
pressing a response button, raising their hand, or providing a verbal response.
7. **Threshold Determination:**
-
**Ascending and Descending:** The procedure typically
starts at a lower intensity level and increases until the patient responds. The
intensity is then decreased until the patient no longer responds. This process
is repeated to determine the hearing threshold at each frequency.
8.
**Frequency-Specific Testing:**
-
**Testing Different Frequencies:** Bone-conduction testing is conducted at
different frequencies to assess the patient's hearing sensitivity across the
speech range.
9. **Interpretation of Results:**
-
**Comparison with Air Conduction:** The bone-conduction thresholds
are compared with the air conduction thresholds to determine the type and
degree of hearing loss.
- **Cross-Hearing Check:** Some
bone-conduction tests may include a cross-hearing check to ensure that
responses are not due to sound being heard through the opposite ear.
10. **Documentation and Reporting:**
-
**Recording Results:** The audiologist records the patient's responses at
each frequency and intensity level.
-
**Analysis:** The audiogram, a graphical representation of
hearing thresholds, is analyzed to identify patterns and characteristics of
hearing loss.
Bone-conduction
audiometry is a valuable tool in audiological assessment, providing essential
information for the diagnosis and management of hearing disorders. It is often
used in conjunction with air conduction audiometry to differentiate between
conductive and sensorineural hearing losses.
